Giant pond of coal ash escapes, floods Tennessee homes

A giant flood of coal ash — the toxic sludge left over after coal burning — broke through an earthen retaining wall at a plant in Harriman, Tenn., Monday. Five hundred million gallons of nastiness flowed into tributaries of the Tennessee River and inundated a dozen nearby homes. Either Santa has it out for Harriman residents, or coal is the enemy of the human race. We’re betting on the latter.
